It's undeniable that Mississippi high schoolers are in dire need of sex education: The state has one of the highest teen pregnancy rates in America, with one third of all babies born to teenage moms, and the statewide chlamydia rate is double the nation's average. But even though 76 percent of Mississippi high schoolers will have sex before they graduate, 81 of the 151 school districts teach abstinence-only, according to the Los Angeles Times.

The others teach "abstinence-plus," which also positions premarital chastity as the best option but also includes contraceptive education. Progressive parents say that the sex education in Mississippi has a long way to go. The law requires that educators tell the students that homosexual activity is illegal in the state, and female and male students are held to a clear double standard.

One example of the former: Students at one high school are asked to pass around an unwrapped Peppermint Patty and see how dirty it got. It's supposed to represent how disgusting a girl becomes after she sleeps around.
